每当我使用@Scheduled调用方法内的存储库时，我总是会收到此错误：Caused by: org.postgresql.util.PSQLException: ERROR: syntax error at or near "."我尝试删除@Scheduled并手动调用该服务并使其正常工作。已经尝试将@Transactional放在方法上相同的结果。我试图将@Transactional分离到另一个类但仍然是同样的错误。有什么想法吗？
编辑： 这个示例代码实际上非常简单。我只是编辑隐私类的名称
@Service
@EnableScheduling
public class SampleServiceImpl implements SampleService {
@Autowired
SampleRepo sampleRepo;
@Scheduled(fixedRate = 10000)
@Override
public void send() {
List<User> users = Lists.newArrayList(sampleRepo.findAll());
}
}
这是日志：
